FASTENER FOR HARVESTING-MACHINE GONVEYER BELTS.

Application filed February 18, 1922. Serial No. 536,121.

To all whom it may concern:

Be it known that I, HUGO CLAUssEN, a citizen of the Republic of Germany, and resident of Bronx, in the county of Bronx and State of New York, have invented certain new and useful Improvements in Fasteners for Harvesting Machine Conveyer Belts (for which I have filed application in Germany February 17, 1921, No. 784,018), and of which the following is a specification.

Conveyer belts for harvesting machines usually have theirends secured to each other by suitable means such as straps and buckles, one end of the belt being made to overlap the other for the purpose of covering these securing means, thus ensuring a continuous smooth surface of the belt.

Heretofore it has been the practice to tie the overlapping portions together along the side edges by means of strings. This occasions great loss of time and is a very inconvenient method. The strings will often becomes loose causing considerable delay, and frequently the conveyer belt cloth is torn or otherwise damaged.

The principal object of my invention is to provide a fastening means which will overcome the difficulties and inconveniences of the method set forth above for securing together the overlapping. portions of a harvesting machine conveyer belt.

Another object of my invention is to provide a fastening means that'will hold the overlapping portions together securely with out any possibility of displacement. A still further object of my invention is to provide readily adjustable means for joining the ends of conveyer belts at their overlapping portions without puncturing or perforating the conveyor belt.

For the accomplishment of these and such further objects as will hereinafter be apparent to those skilled in the art to which this appertains, the invention consists in the construction, combination and arrangement of parts herein specifically described and illustrated in the accompanying drawings, wherein is shown a preferred embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the claims hereunto appended.

In the accompanying drawings, on which similar reference characters indicate corresponding parts:

Fig. 1 is a perspective view of part of a harvesting machine, showing my fastener secured to the conveyer belt; 7

Fig. 2 is a perspective view of the fastener;

Figs. 3 and 4 are detail views of different forms of, my invention.

Referring to the construction in further detail, a refers to the frame; 6 is one end of the conveyer belt to which the buckles are fastened, 0 represents the straps fastened to the conveyer belt, d is the overlapping end of the conveyer belt.

In Fig. 2 is shown a perspective view of my fastener. The fastener is stamped out of spring sheet metal or other suitable material in U-shaped form, indicated by reference letter 6 in the drawing. A tongue f is riveted or otherwise secured to the U-shaped member and thus two superposed clamping spaces g and h are formed. Two of the fasteners f are clamped along the edges on either side of the conveyer belt portion 6, the conveyer belt cloth entering into the space g of the fasteners. The overlapping portion of the conveyer belt d is then inserted in the space 72. of the fasteners and is held securely in position by the spring clamping effect. The fasteners can be slid along the sides of the overlapping portion d until the fastener is flush with the end of said overlapping portions. In the cases of changes in the conveyer belt cloth due to stretching the fasteners can be suitably adjusted, when necessary. The innor surfaces of the fastener may be serrated or roughened so as to obtain a better hold on the conveyer belt cloth.

The fastener shown in Fig. 3 is substantially the same as the fastener of Fig. 2, but contains in addition a projecting pin 2' secured to the middle blade. On the lower surface of the overlapping conveyer belt portion d eyelets 7c are provided which are adapted to engage the pins 2' and thus ensure a better hold.

In the modification shown in Fig. 4: the U shaped metal piece Z is provided with two upwardly projecting ears m in which is pivoted a tongue member 42. having a downwardly projecting serrated or toothed edge 0. The overlapping portion d of the'conveyer belt is inserted in the fasteners While the tongue 91 is swung upward. The

tongue at is then pressed down causing the teeth to engage the conveyer belt cloth and holding'it securely in position.

It will be apparent from the foregoing description that by the use of my readily adjustable fastener much tiinewill be saved, and the belt held together with greater security than has been possible under the old system of tying with strings. No damage is done to the belt while under the old method the beltwas often torn or otherwise damaged.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent, is

l. A detachable spring metal conveyer belt fastener adapted to hold together two overlapping pieces of belting along their aligned edges, said fastener having a U- shaped portion adapted to frictionally engage one of said overlapping pieces and clamping means secured 'tosaid U-shaped portion constructed and arranged to cooperate with said U-shaped portion to engage the other piece,

shaped portion constructed and arrangedto ,frictionally engage and clamp the other of said overlapping pieces against said U- shaped portion of the fastener.

3. A detachable spring metal fastener adapted to hold together tWo overlapping" pieces of thin flexible material along their aligned edges, having a Ushaped portion adapted to frictionally engage one of said overlapping pieces, and a projecting spring tongue spaced from and overlying sai shaped portion constructed and arranged to engage the other of said overlapping pieces, a projection extending from said U-shaped portion into the space between said portion and said tongue, said projection adapted to engage a suitable eyelet'in said other overlapping piece.

Signed at New York in the county of New York and State of New Yorkthis 28 day of January A. D. 1922.
